Hello Xiaorong,
Are you familiar about making ROOT shared library? If not,
my explanation was not kind enough.
> noinst_HEADERS = \
> ParticleDict.h ParticleLinkDef.h \
> DimuonDict.h ParticleLinkDef.h
Normally, you need to put those #pragma statements in
LinkDef.h file and it must be after '#pragma link off all classes;'.
Then, of course you have to regenerate and recompile the
dictionaries. For more detail, please read ROOT documentation
about compiling shared library.
Thank you
Masa Goto
